To dit' whom t may concern. l

Be it known that l, blomus Davinson, a citizen et the United States,residing at Cambridge, in the county et Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inCofice-Pots, or which the following isa specification, reifer-encebeing` had to the accompanying drawings.

rllhis invention relates to improvements in coitee percolators and isparticularly designed to increase the etiiciency ot devices in currentuse and to provide a percolator ot strongl and simple construction.

One ot the objects oit the invention is the production of a coli'eepercolator having1 its parts so arranged that the same may be quicklycleaned when desired and which is adapted to rive efficient service.

lllith the above and other objects in view this invention comprisescertain constructions, combinations and arrangements et parte describedin the following; spccication and illustrated in the accompanyingdrawings, in which:

liigure 1 is a vertical sectional view, liigg. 2 a detail perspectiveview oil" a spray member, and, it 3 is a detail perspective view of aninner receptacle. v

Referring to the accompanying drawings numeral 1 denotes a mainreceptacle which is provided with a handle 2, and formed with a spout 3,in the conventional manner. Located on the bottom d oi the receptacle 1is an inner receptacle IS which. is formed with an upwardly projectinghollow coneshaped head 6 and a port 7 through which svater or otherfluid in the receptacle 1 is adapted to flow into the :inner receptacle5. The upper edge oi the receptacle 1 is preferably formed with a rim 8and a porcolator 9, formed of glass or other material, is suit ablypositioned on the rim 8. The percolator 9 is provided with a handle 10and a removable cover 11 and has its bottom 12 formed with a series ofsmall openings. EX- tending vertically through the bottom 12 is aconducting tube 13 which is closed at its upper end by a cap 1d andformed with lateral ports 15, located near said upper end, and withdeliecting hoods or spray members 15 which are positioned over theopenings or ports 15 so as to deflect water rising in the tube evenlyover the bottom 12 oi the percolator. The lower end of the tube 13 titclosely over the cone-shaped head G of `the inner receptacle 5, and saidtube is ei :tectively braced against lateral displacement by braces 1Gwhich are secured thereon and connected at their upper ends to the lowerside ot the bottom 12 of the percolator. In order to securely hold thepercolator 9 on the receptacle 1, a flange 17 is formed on the lowerportion ot the same.

In using my improved percolator for the production et' a cotlee drinkthe receptacle 1 is iilled with a proper amount of water and thepercolator 9 is provided with a suitable quantity of coffee, and thedevice placed over a stove or heater. The water ot the receptacle 1 willflow into the innerreceptacle 5 and as the water contained therein willbecome heated more rapidly than the balance of the water the same willrise in the cone-shaped head 6 and the tube 13, and pass into thepercolator, after being sprayed or deiiected therein by the hoods 15',so as to completely saturate the coltee. The liquid passes back into themain receptacle 1 througl'i the perforations 12 in the bottom olf thepercolator t). When it is desired. to eiiect a perfect iiltration oitthe cottee drinlr a sack or textile iilter 18 may be secured around thebraces 16.

It is obvious that the percolator 9 maybe readily removed from the mainreceptacle 1 without any dii'liculty, and when removed may be readilyreturned to ita normal position thereon. rlhe inner receptacle 5 isadapted to hold the water entering; through the port 7, which port islocated on the receptacle 5 below the plane of the upper end oi the conehead 6, so that said water will,

when suiliciently heated, flow upwardly through the tube 13 into the4percolator, thereby establishingI a circulation within the mainreceptacle.

Having described my invention, I claim:

The hereindescribed coiiee pot comprising a main receptacle having aspout and a handle, a percolator body removably arranged on the open topof the receptacle and ,having a perforated bottom and a handle, aremovable cover for said body, a cone-shaped inner receptacle arrangedupon the bottom ol the main receptacle and having adjacent to one edge aliquid inlet open-ing and at its center an integral upwardly projectingconeshaped head, a tube projecting through the center ot the perforatedbottom of the percois formed tunnel shaped and is adapted to later bodyand iixed therein, thelower end of end of sadftube' abovese'd Openings,(spray.
